Abstract

Systems, devices, methods, and compositions that improve the scent perception for a user. Improved scent perception is achieved by presenting alternating scents and by varying levels of output of scents, as well as by minimizing device clogging, thereby improving evaporation profiles.

Description

The present invention also relates to incense Ri distribution kit. The present invention delivers to the user a scent experience with little decay over time. The present invention thus provides the user with a scent experience that can be more easily noticed over a longer period of time.

  It is generally known to use electrical devices to evaporate a perfume and / or fragrance composition into a space, particularly a home space, such as a living room, to provide a pleasant fragrance. For example, AIRWICK® Diffuser ACTIF® (manufactured by Reckitt Benckiser) or AMBI-PUR® fragrance diffuser Various such devices are on the market, including (Sara Lee manufactured). In general, these devices consist of a perfume or fragrance source, an electric heater, and a power supply. By applying heat to the fragrance or fragrance source, the fragrance or fragrance is continuously fed into the space in which the device is located.

  The problem with this arrangement is that the person who occupies the space immediately gets used to the fragrance or fragrance, and after a while, does not perceive the fragrance strength as much as the actual strength, and may not notice it at all. That is. This is a well-known phenomenon called habituation. Solutions to this problem have been sought.

  One approach to addressing this problem is described in US Pat. The Whitby et al patent application is adapted to provide two or more fragrance compositions in space, wherein at least one of these fragrance compositions is provided periodically. An apparatus is disclosed. The method and apparatus may provide a continuous supply of the first fragrance composition and a periodic supply of the second fragrance composition. This fragrance composition (s) may be volatilized by heat and may include a deodorant and / or an insecticide compound. These fragrance compositions are preferably selected such that the two fragrance compositions are in contrast to each other or have different notes. This fragrance composition is generally sent rhythmically from an apparatus equipped with a heater. The periodic supply of heat to release the fragrance composition is controlled by providing this device, in particular a heater with a control device. This control device is in the form of an electrical circuit. This controller is adapted to operate the heater "with a suitable interval of time" between them for a short period of time, preferably 15 seconds to 15 minutes.

US Patent Application Publication No. 2002/0159916

  However, Whitby et al.'S patent application maintains or sustains the olfactory effect of a continuously released fragrance composition rather than giving the user a noticeable fragrance change. It is clear that this is the main direction. In addition, Whitby et al.'S patent application mentions the periodic supply of two or more fragrances, but the user is more individual than a single fragrance that is a blend of two compositions. There is no specific teaching on a release pattern or program that directs the delivery of different fragrances in relation to each other so that they can actually experience the fragrances.

(Characteristics and advantages of the invention)
The inventors have found that the decrease in the user's scent perception is not solely due to the well-known habituation phenomenon, but the physical, mechanical, and / or Or it was discovered that it was also caused by chemical changes. In particular, during use, it has been found that the release from the wick decays as a function of time, at least in part due to clogging of the wick. Clogging of the wick reduces volatilization (or evaporation) and thus reduces perception of perfume components. This clogging phenomenon can be caused, for example, by chemical reactions in the perfume composition and by gradual but selective evaporation of perfume components that do not cause clogging. The present invention addresses these issues.

  In some embodiments, the present invention provides the user with a perfume experience that is more noticeable and consistent over time when compared to existing products. In some embodiments, the present invention reduces the adaptation / habituation effect by alternating fragrances. In other embodiments, the present invention provides more efficient fragrance release characteristics of one or more perfumes. In yet other embodiments, the present invention reduces the effects of adaptation / habituation and provides more efficient perfume release characteristics. The present invention provides the user with a perfume experience that can be noticed for a long time.

Reference will now be made in detail to the present embodiments (representative embodiments) of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

  The present invention relates to a method, apparatus and system for releasing volatile compositions as well as novel compositions. In some embodiments, the present invention relates to a method and apparatus for releasing two or more volatile compositions. In some embodiments, the present invention relates to releasing one or more volatile compositions. There are numerous embodiments of the methods and apparatus described herein, all of which are intended to be non-limiting examples.

  The method for releasing a volatile composition can include a variety of different embodiments. Volatile compositions can be fragrance compositions, insecticides, air fresheners, deodorants, aromacology, aromatherapy, compositions that function as insecticides, or adjust, change, or otherwise fill the atmosphere, or It can be any other substance that acts to change the environment. The volatile materials released in a given embodiment of the method can be the same type of material (eg, two or more fragrance compositions) or they can be different types of materials (eg, fragrances). Agent composition and air freshener). The deodorant or malodor control composition may contain a substance selected from an odor neutralizing substance, an odor blocking substance, an odor masking substance, and combinations thereof. The method can release volatile compositions in a procedure where the release of different volatile compositions automatically alternates between those different volatile compositions.

The composition can include components suitable for use in a volatile composition discharge device. The components are not limited and can be selected based on their Kovats Index ("KI"; as determined with 5% phenyl-methylpolysiloxane as the nonpolar silicone stationary phase). The Kobats Index places the volatile attributes of an analyte (eg, a component of a volatile composition) on that column in relation to the volatile properties of the n-alkane series on that column. . Typical columns used are DB-5 and DB-1. According to this definition, the KI of normal alkanes is set to 100n (where n = number of C atoms in the n-alkane). Next, the analyte x eluting at time t ′ between two n-alkanes having “n” and “N” carbon atoms and having corrected retention times t ′ _n and t ′ _N respectively. The KI of is calculated as:

非極性からわずかに極性のＧＣ固定相上では、被分析物のＫＩはそれらの相対的揮発性と相関している。例えば、小さなＫＩを有する被分析物は、大きなＫＩを有するものよりもより揮発性である傾向がある。被分析物をそれらの対応するＫＩ値で順位付けすることにより、液体−気体分配系における被分析物の蒸発速度の良好な比較が与えられる。本発明に従う揮発性組成物は、約１８００、１７５０、１７００、１６５０、１６００、１５５０、１５００、１４５０、１４００、１３５０、１３００、１２５０、１２００、１１５０、１１００、１０５０、１０００以下、又はそれよりも小さいＫＩを有することができる。本組成物は、定義されたＫＩを有する前記構成成分を、約７０重量％、８０重量％、９０重量％、９１重量％、９２重量％、９３重量％、９４重量％、９５重量％、９６重量％、９７重量％、９８重量％、９９重量％以上、又はさらに高い割合で、含むことができる。

On non-polar to slightly polar GC stationary phases, the KI of the analyte correlates with their relative volatility. For example, an analyte with a small KI tends to be more volatile than one with a large KI. Ranking the analytes by their corresponding KI values provides a good comparison of the evaporation rates of the analytes in the liquid-gas distribution system. Volatile compositions according to the present invention are about 1800, 1750, 1700, 1650, 1600, 1550, 1500, 1450, 1400, 1350, 1300, 1250, 1200, 1150, 1100, 1050, 1000 or less, or smaller. Can have a KI. The composition comprises about 70%, 80%, 90%, 91%, 92%, 93%, 94%, 95%, 96% of the component having a defined KI. Wt%, 97 wt%, 98 wt%, 99 wt% or more, or even higher.

  The release of volatile compositions can be controlled and optimized by adjusting the core temperature. The evaporation rate is related to the core temperature. This is described using a gas-liquid partition coefficient as defined below:

式中、Ｃ_liは被分析物ｉの液相濃度であり、Ｃ_giは被分析物ｉの気相濃度である。次いでＫは次式として記述できる：

_Where C _li is the liquid phase concentration of analyte i and C _gi is the gas phase concentration of analyte i. K can then be described as:

したがって、温度が高くなると、被分析物のＧＣ保持は低下することになる。あるＫＩ範囲内の揮発性組成物に適応するように芯の熱を調節するためには、１００ＫＩ単位のＫＩの増加に対して１０℃の芯温度の増加が得られるように、芯に熱を加える。

Therefore, the GC retention of the analyte decreases as the temperature increases. To adjust the core heat to accommodate volatile compositions within a certain KI range, heat the core to an increase in core temperature of 10 ° C. for an increase in KI of 100 KI units. Add.

  In some embodiments, a volatile composition for use at a core temperature of about 60 ° C. has about 80% by weight of the component having a KI of less than about 1600 and about 15% by weight of the component is 1600%. Components that have a KI greater than 1800 and less than 5% by weight of the component have a KI greater than 1800. An example of such an embodiment is a floral perfume composition as shown in Table 2, in which 80.5% by weight of the component has a KI of less than about 1600, and 15. 0% by weight has a KI greater than 1600 and less than 1800, and 4.5% by weight of the constituents have a KI greater than 1800.

  In some embodiments, a volatile composition for use at a core temperature of about 40 ° C. has about 80% by weight of the component having a KI of less than about 1400 and about 15% by weight of the component is 1400%. Components are included so that they have a KI greater than 1600 and less than 5% by weight of the components have a KI greater than 1600.

幾つかの実施形態では、揮発性組成物はある期間の間単一の供給源から放出され、その後のある期間の間放出が低減される。このように、本発明は、揮発性組成物の放出の「オン」と「オフ」の間で順に交代させる、又はトグルスイッチを切り替えるように企図されている。

In some embodiments, the volatile composition is released from a single source for a period of time and the emission is reduced for a period of time thereafter. Thus, the present invention contemplates alternating between “on” and “off” emission of volatile compositions or switching a toggle switch.

  The duration of release can range from as short as about 15 minutes to as long as about 48 hours. Intermediate periods of release are 20, 25, 30, 35, 40, 45, 50, 55, and 60 minutes, and 2, 3, 4, 5, 6, 12, 18, and 24 hours, As well as any other intermediate time. Of course, the release period can range from any listed time to any listed time, for example, from 20 minutes to 24 hours, or from 30 minutes to 1 hour. One specific example of a release period is 30 minutes. Another example is 45 minutes.

  The period of reduced emission can be varied as well. It can range from as short as about 15 minutes to as long as about 48 hours. The intermediate periods of reduced emissions are 20, 25, 30, 35, 40, 45, 50, 55, and 60 minutes, and 2, 3, 4, 5, 6, 12, 18, and It can be 24 hours, as well as any other intermediate time. Of course, the duration of the reduced release can range from any listed time to any listed time, for example, 20 minutes to 24 hours, or 30 minutes to 1 hour. . One particular example of a reduced release period is 30 minutes. Another example is 45 minutes.

  Reduced release can be characterized by some decrease in release. The decrease in emissions can be measured quantitatively, for example, by reducing the weight (mg) of volatile composition delivered to the surrounding environment per unit time, or, for example, by user perception It can be measured qualitatively. The reduction can be small or large, and can result in minimal or no release at all. That is, emissions can be reduced to their natural level, ie, the level of emissions that occur without the presence of intentionally applied external energy applied to the system (eg, electricity in the form of heat) Typical ambient temperatures for the environment are from about 65 ° F to about 75 ° F (about 18 ° C to about 24 ° C).

  The present invention contemplates that more than one volatile composition can be released. The two or more compositions can be the same or different. Different compositions may exhibit the same or different properties, such as the same fragrance or different fragrances, or fragrance and malodor control.

  The release of two or more volatile compositions can be performed such that the two or more compositions are released at the same time or at different times. Thus, in some embodiments, the release of two or more compositions can overlap entirely. On the other hand, the emissions can also be designed so that they do not overlap at all. And release can also be designed so that there is very little overlap in release time to very long overlap in release time. For example, the overlap of release times can be as short as 0.1 seconds to as long as 48 hours. Release is such that when one composition is released, the second composition is not released, and when the second composition is released, the first composition is not released. Can be designed. Thus, the present invention contemplates alternating the release of two or more compositions or switching with a toggle switch.

  As noted above, the release of volatile compositions can occur from a short period of time, such as 15 minutes, to a long time period, such as 48 hours. Release can be any time in between, and in some embodiments, the release of the volatile composition is 30 minutes. In other embodiments, the release of the volatile composition is 45 minutes. If more than one composition is released, the first composition can be delivered for 30 minutes (“on”) and no second composition can be delivered (“off”) during that time. For the next 30 minutes, the first composition is off and the second composition is on. Of course, it can be ramped on and / or off so that there is some overlap in the release of the composition between the ramp phases.

  Of course, the two or more volatile compositions can be released in any suitable order. The order of release of volatile compositions can be a pattern or random. As used herein, the term “pattern” refers to a repeating order. In embodiments where the order of release of the different volatile compositions is repeatable, the pattern can be repeated once or any number of times after the initial order. As used herein, the term “random” refers to an order in which the order of emission of volatile compositions is not repeated in a regular manner. It is also possible that the release procedure includes some time in which the order is in a pattern and some time in which the order is random.

  In some embodiments, two or more volatile compositions are released in an alternating order. For example, a first volatile composition and a second volatile composition can be present, and the first volatile composition is released in alternating periods with respect to the second volatile composition. That is, if the first volatile composition is represented by “1” and the second volatile composition is represented by “2”, these volatile compositions are 1, 2, 1, 2,. Can be released in an alternating pattern such as FIG. 1 schematically shows such a release program. In FIG. 1, this diagram represents the period during which these volatile compositions are exposed (or “activated”) to an energy source (eg, the heat with which they heat the composition). If in a device with a heater, the diagram can represent the period during which the heater is turned on and off). When three volatile compositions are present, they are emitted in an alternating pattern such as 1, 2, 3, 1, 2, 3,... As shown in FIG. obtain.

  In viewing these figures (and the accompanying diagrams), it should be understood that these are non-limiting embodiments. In other embodiments, a separate volatile source (such as a heater) is not required for each volatile composition. There can be any suitable number of volatilization sources for the volatile composition. For example, a single volatilization source can be used to volatilize more than one volatile composition. Such volatile sources can be moved, for example, to volatilize different volatile compositions, or (open or close a door or gate between the volatile source and a given volatile composition. It may be possible to selectively induce energy (eg, heat) to different volatile compositions. Alternatively, the storage tank can be movable with respect to the volatile source (eg, so that the storage tank can be selectively moved over the heater).

  As used herein, the term “interval” refers to the shortest period in the release procedure. As used herein, the term “individual emission periods” can refer to individual periods in which a given volatile substance (or combination of volatile substances) is released in an emission sequence. This may generally correspond to the period during which, for example, the heater is turned on for a given volatile substance or combination of volatile substances (provided that there is only a small amount of time between the operation of the heater and the emission of volatile substances). There may be a significant time difference). Individual release periods can also refer herein to a first period, a second period, etc., each of which has a start and an end. As used herein, the term “injection” refers to a volatile composition after the hot core is maintained at a reduced temperature to allow back flow of at least one component of the volatile composition. Refers to the initial and peak release. It should be understood that the different volatile compositions need not be released over an equal period of time. For example, after one volatile composition is released, a different volatile composition can be released for a shorter period or a longer period. In another example, after one volatile composition is released, another interval of the same volatile composition can follow before the different volatile composition is released. If different volatile compositions are not released for an equal period of time, it may be desirable to increase the amount of composition with a longer cumulative time release so that the volatile compositions are emptied at about the same time. is there. There are many possible alternate discharge sequences. For the three volatile compositions, non-limiting examples of some other possible emission patterns include (1, 2, 2, 1, 3, 3); (1, 2, 3, 3, 2, 1) And (1, 2 2 2 2, 1 1, 3, 3 3 3, 1), but is not limited thereto.

  In some embodiments of the method, the volatile composition can be released during individual release periods that are about 15 minutes or less, although it may be more desirable that each release period be longer than 15 minutes. is there. In the case of scented substances, longer periods may be more desirable. In one embodiment of the method, the volatile composition is alternating between individual periods of more than 15 minutes each and not more than about 12 hours, or not more than about 24 hours, or not more than about 48 hours, or longer. To be released. Every numerical range recited throughout this specification includes all narrower numerical ranges that fall within the wider numerical range as expressly set forth herein. Thus, in another non-limiting embodiment, the volatile composition is alternately released for periods longer than 15 minutes or greater than about 1 hour and less than 2 hours. In one embodiment, each volatile composition is released for a period of about 72 minutes. In one embodiment, each volatile composition is released for about 30 minutes.

  Volatile compositions may be released so that one follows immediately after the end of the emission period of the other. In other embodiments, the volatile compositions are released such that there is an interval between the end of the emission period of one of them and the start of the emission period of another volatile composition. Can do. FIG. 3 is a diagram illustrating one non-limiting embodiment of an emission program for emitting two volatile compositions, where there is an interval between emission of volatile compositions, where “G” indicates an interval. In other embodiments, the volatile composition can be released such that there is an overlap in the emission period of two or more volatile compositions. FIG. 4 is a diagram illustrating one non-limiting embodiment of an emission program for releasing two volatile compositions, where there is an overlap of emission of volatile compositions, where The symbol “&” indicates the release period during which both volatile compositions are released. FIG. 5 shows one non-limiting embodiment of an emission program for releasing three (or more) volatile compositions, with one volatile composition emission and two other volatile compositions. There is an overlap with the release of the sex composition. In other embodiments, one or more volatile compositions can be released continuously and another volatile composition can be released for a period longer than 15 minutes.

  If it is desirable to have an interval between the end of the emission time of one of the volatile materials and the start of the emission period of another volatile material, the interval can be any suitable duration. The interval period between the release of volatile substances may be longer than 0% up to 100% or longer than the duration of the previous or subsequent release period. If it is desired to have an overlap during the emission period of two or more volatile materials, the overlap can be of any suitable duration. The duration of the subsequent release of the volatile material may overlap up to 100% longer than 0% of the time during which the first volatile material is released. In certain embodiments, for example, it may be desirable to have an overlap of about 25% between different volatile materials. For example, instead of releasing the scent substance “A” for 60 minutes and then releasing the scent substance “B” for 60 minutes, the scent substance “A” is released for 45 minutes, and then the scent substances “A” and “B”. Both can be released for 30 minutes and then the scented substance “B” can be released for 45 minutes, where 30 minutes is the total release time of the scented substances “A” and “B” and their combinations ( That is, 25% of 120 minutes).

  The interval or period of overlap can be controlled automatically. In certain embodiments of the article (s) or device (s) used to emit volatile material, the article (s) or device (s) may include a user at any interval during the release period and / or Alternatively, a control device can be provided to allow the duration of the overlap to be controlled. The overlapping procedure can be used for any purpose, for example, where it is desirable to allow the user to smell not only the individual fragrance material for one period but also the blended fragrance material for another period. Also good.

  In certain embodiments, it may be desirable for the method to be operated by article (s) and / or apparatus (s) that do not use flames (eg, are not candles). In certain embodiments, it may be desirable for the method to operate independently of other media (such as, but not limited to, movies, televisions, etc.). . In other embodiments, it may be desirable to operate the method in a coordinated manner with other media.

  There can be any suitable emission program or scheme for releasing a volatile composition. In certain embodiments where scented material is being released, it is desirable for the device to provide an alternating scent experience rather than a sustained impression of a single scent. In one embodiment, a day / night release program is provided in which one scent is provided to wake a person and another scent is provided for a period of time while they are going to sleep Sometimes it is desirable. Thus, in some embodiments, it may be desirable to deliver the same scented substance daily at the same time. In other embodiments, it may be desirable to avoid a routine scent experience. For example, if the release pattern is not synchronized over 24 hours, it is desirable that the user have a different scent experience at a given time during the day or night of each 24 hour period There is also. Many other embodiments are possible.

  A total release program (or simply “release program”) refers to the overall sequence of individual release periods from start to finish. In certain embodiments, it is desirable for the release program to be continuous. The term “continuous” when used in connection with a release program means that once the program is started, there is a planned release sequence over the entire period. This release program can include a period in which there are intervals in the release, as described above. Although there is not necessarily a continuous release of the volatile composition, it is still considered a continuous emission program. However, it should be understood that the release program can be interrupted (eg, switched off) by the user if desired. That is, the method can provide a user interface, which can provide the user with the ability to interrupt the release program. In certain embodiments, the emission program may be designed to operate continuously or nearly continuously until at least one of the volatile compositions is substantially empty. In certain embodiments, the emission program is desirably operated continuously until all volatile compositions are substantially emptied, and this desirably occurs approximately simultaneously. The release program can have any suitable length, including but not limited to 30 days, 60 days, or shorter or longer periods, or any period between 30-60 days.

  One example of a device that can be used in accordance with the present invention is one that comprises a wick. When using such a device, the wick acts as a conduit for carrying the volatile composition from the reservoir to the point of release. The wick is generally porous or contains pores that provide a flow of the volatile composition. The core can be made from a variety of materials, including but not limited to cellulosic fibers, metals, plastics, ceramics, graphite, and fabrics. Synthetic materials such as plastics may be desirable because of their uniform performance. Plastic materials that can be used to form the porous core include high density polyethylene (HDPE), polytetrafluoroethylene (PTFE), ultra high molecular weight polyethylene (UHMW), nylon 6 (N6), polypropylene (PP), poly Vinylidin fluoride (PVDF) and polyethersulfone (PES) can be mentioned but are not limited to these.

  Cores can be described in terms of their average pore size. The core may have any suitable pore size. US patent application 2002 / 0136886A1, entitled “Porous Wick for Liquid Vaporizers” describes a standard method for measuring pore size. In certain embodiments, the average pore size of the core useful in the present invention ranges from about 10 microns to about 500 microns, or from about 50 microns to about 150 microns, or from about 60 to about 100, or about 70 microns. It is. The core can have an average pore volume of about 15% to about 85%, or about 25% to about 50%. Similarly, the wick depends only on the desired application and can vary in length. In certain embodiments, the core can be as short as 1 mm or as long as 100 mm, or longer, or any length in between. The core can range in length from about 5 mm to about 75 mm, or from about 10 mm to about 50 mm.

Should be understood. Volatile compositions important herein include solids, liquids, gels, capsules, wicks, and carrier materials such as porous materials impregnated or containing volatile materials, and combinations thereof. Any suitable form can be used without limitation.

  In the case of scented substances or fragrances, different scented substances can be similar, related, complementary or contrasting. However, scented substances may not be desirable to be too similar if those different scented substances are used to avoid the problem of habituation to the scent, otherwise they will experience the scent. People may not be aware that different scents are emitted. Different scents can be related to each other by a common theme or in some other manner. For example, the different scents can all be floral scents, fruit scents, and the like. Examples of different but complementary scented substances may be a vanilla scent and a French vanilla scent.

  The present invention also includes a method that provides consumers with a selection of compatible volatile compositions, such as fragrance compositions. In one embodiment, such a method includes providing a fragrance composition for use in one or more release devices. More specifically, in one embodiment, the method provides a consumer with the selectivity of two or more fragrance compositions in a reservoir configured for use with one or more release devices; And providing some sort of indication that tells the consumer which of the two or more fragrance compositions is compatible for use together.

The device controls the user's release period of one or more volatile compositions and / or the time between the release of different volatile compositions or the overlap period of volatile substances. A control device can be provided to enable this. For example, in one non-limiting embodiment, if the device is equipped with the ability to release each volatile material for a period greater than 15 minutes and not longer than 48 hours, the device may have one or more users. A controller can be provided that allows the emission period for the volatile composition to be set, for example, 30 minutes, 45 minutes, or 72 minutes, or 1 hour.

  The device can be provided with an additional user control device. The apparatus can include a temperature regulator or other switch to allow the user to adjust the temperature setting of the heat source for one or more volatile compositions. The setting may be predefined for a particular volatile composition or may be adjusted based on the selected temperature to be applied to the core.

  The device can also be sold in the form of a kit that includes the device and one or more reservoirs of volatile compositions. This device and / or kit may also place instructions for use instructing the user about a specific release period that may be used to produce a specific result, and / or where in the given space. Instructions about what to do can be included. For example, the instructions may include instructions for setting the device based on the size of the room, vehicle, etc. in which the device is placed. Such instructions may also include instructions to the user to select more frequent changes between the release of the scented material in order to recognize the scent more strongly. Instructions may also be provided to specify how to operate the device in conjunction with other devices. The instructions can be provided in any suitable form, eg, written, audio, and / or video.

  The device can also be powered by a battery so that it does not need to be plugged into an electrical outlet. The device can also be configured to be both connected to a current source and powered, and also powered by a battery. The device can also be provided with an adapter that can be plugged into an automotive cigarette lighter. In addition, the device allows the user to control any or all of the emission characteristics of the device, including but not limited to changes in the emitted volatiles, without touching the device. A remote control device can be provided to enable.

  The apparatus may include a microprocessor having fewer components than an analog circuit and having improved circuit quality for each lot number. The microprocessor allows the user to program and control the temperature characteristics by adjusting the operation to change. If desired, the microprocessor may be connected to a user interface. This can be any suitable type of user interface. Examples of user interface types include, but are not limited to, LCD screens and LEDs. In addition, the microprocessor allows components to communicate with each other a plurality of devices (such as those located in different parts of a room or those located in different rooms). For example, the microprocessor may allow the remote control device to send a digital signal via an infrared beam to turn on or off another device.

  Many other types of devices are possible. For example, in other embodiments, the methods described herein can operate with more than one dispensing device. Such dispensing devices include any type of dispensing device, including but not limited to aerosol nebulizers. FIG. 12 shows one non-limiting embodiment of an array of aerosol nebulizers 80 and 82. The aerosol nebulizer used in such a manner can function in any suitable manner. In some embodiments, the aerosol nebulizers may each operate independently, such as with timer 84 to switch the emission of volatile materials in the manner they are desired. The distribution device can be powered in any suitable manner, such as by a battery 86. Dispensing devices 80 and 82 may be placed adjacent to each other, or they may be placed in different parts of the space where it is desired to emit its volatile material. FIG. 13 shows another non-limiting embodiment of the dispensing device 88. In FIG. 13, the dispersion device 88 is a single device that includes two (or more) dispensers, such as aerosol sprayers 90 and 92. Device 88 may be operated by one or more timers, or sensors 96, and may be powered by one or more batteries, or other power source.

  In some embodiments, the device can be configured to be turned on and off in response to some stimulus, such as by a sensor that responds to light, sound and / or movement. For example, one of the devices can be configured to be turned on when the light is felt, and another device can be set to be turned off when the light is felt. In another example, a microprocessor can be used with a motion sensor to operate a device (eg, a heater and / or a fan in the device). For example, the device can be turned off until a person moves near the motion sensor. The device can then be turned on when a person walks in the vicinity of the motion sensor. The use of a microprocessor provides flexibility in controlling the volatile emission characteristics. This is because the microprocessor can be replaced if it is desired to change the emission characteristics. Replacing the microprocessor eliminates the need to modify the entire circuit.

  While particular embodiments of the present invention have been described, it will be apparent to those skilled in the art that various changes and modifications can be made to the invention without departing from the spirit and scope of the invention. Furthermore, while the invention has been described in connection with certain specific embodiments, this is for purposes of illustration and not limitation, and the scope of the invention is defined by the appended claims. This should be considered as broad as the prior art allows.

Example 1: Perfume evaporation in plug-in devices decreases over time Long-term exposure to scented substances creates a habituation effect that makes it difficult for a person to recognize the presence of a particular perfume even at the same concentration This is known in the art. This phenomenon occurs with the use of commercially available scent release devices.

  However, the applicants consider that in addition to the phenomenon of habituation, a decrease in the scent substance output over time by a commercially available device causes the user to not recognize the scent. To test this hypothesis, a commercial product grade (GLADE®) Sky Breeze® was plugged (ie, turned on) to release the scented material over an extended period of time. The evaporation rate (or release rate) was determined by measuring the starting content of the device and making daily measurements to determine the amount lost.

  FIG. 14 shows the results of the study. As can be seen from the figure, the evaporation rate decreases significantly with time. In fact, the evaporation rate dropped by nearly 50% after only one week of use. In addition, there is a visual difference between a continuously used core and a toggle-controlled core. (See FIG. 15, which shows a photograph of a wick used continuously for 21 days with a photograph of a wick that was turned on and off for 42 days with a toggle switch.

Example 2: Clogging of the core causes a decrease in evaporation rate The observed decrease in evaporation rate is caused by a number of factors, including selective evaporation of more volatile compounds and clogging of the core. It was. Further studies were conducted to determine the mechanistic reason behind the decrease in evaporation rate.

  The GLADE® Vanilla Breeze® and Hawaiian Breeze® perfume equipment were turned on for 28 consecutive days. At the end of 28 days, the wick was removed from the apparatus and frozen in liquid nitrogen. Samples were taken from the top, middle and bottom of the core. At the same time, the volatile composition remaining in the storage tank was sampled. The sampled volatile compositions were analyzed by gas chromatography to determine their Kovats Indices. 16 and 17 schematically show the result.

  As can be seen from FIG. 16, the wick changes visibly over the test period. The bottom of the wick is lightest in color and the wick becomes darker toward the top. This is also evident in the photograph of FIG.

  FIG. 17 shows exactly what happens when the core is clogged. There was little difference between the different components in the contents of the storage tank, and the low, medium and high volatile components were hardly different from the controls and little difference from each other. The same was observed for the bottom and middle of the core.

  However, the top of the core showed a marked difference. High volatile compounds were almost depleted and intermediate volatile compounds were slightly higher than controls. Most notably, less volatile compounds were collected on the top of the core than 150% more than the control. The volatile compound population at the top of the wick (the main site of volatilization) was biased towards a very low volatility component. Thus, these low volatility components effectively suppressed the evaporation rate and were substantially “clogging the wick”.

  Without being bound by theory, what is happening is the accumulation of low volatility material at the top of the wick, which causes the more volatile material to move to the top of the wick and evaporate. It is hindered. At the same time, the compounds in the volatile composition having higher volatility selectively evaporate, and the compounds having lower volatility are concentrated at the top of the core, thereby further aggravating the clogging phenomenon. Thus, for a number of reasons that may be additional or even synergistic, the evaporation of volatile materials decreases rapidly during long term use of the core device. The energy continuously applied to the device in the form of sustained heat to the wick causes these less volatile compounds to move against the concentration gradient and force them to accumulate at the top of the wick . Release from commercial plug-in products showed a drop of about 50% during only one week of use. (See FIG. 14.) Volatile components by deliberately switching the toggle switch of the thermal core device to the “off” state, or by introducing an interval between the release of single or multiple core devices. Diffuses inside the core and reaches an equilibrium concentration close to the composition of the volatile component mixture in the reservoir. Thus, turning the toggle switch “off” or providing spacing during discharge by removing heat from the wick normalizes the concentration gradient that “clogs” the wick.

Example 3: Toggle switching reduces clogging and improves evaporation rate When it is discovered that the decrease in evaporation rate was due to clogging of the wick, steps were taken to solve the problem. It was. Surprisingly, allowing a quiescent period for the wick evaporator (generally by reducing the heat applied to the wick) causes a back-flow of volatile substances inside the wick, thereby making it more volatile. It has been discovered that low components can flow through a concentration gradient and return to equilibrium. At the end of the downtime and the backflow of less volatile components occurs, energy is reapplied to the system for a limited period of time, during which time the volatilization of the composition occurs again. This cycle can be repeated any number of times.

FIG. 18 shows that the evaporation rate can be significantly improved by turning the single core device on and off with a toggle switch. Briefly, FIG. 18 shows two evaporation curves for a commercial product, GLADE® Sky Breeze®, which are operated in two different ways. It was. One device was kept in a continuous state for approximately 4 weeks (“no toggle control”). The other device was cycled on and off ("toggle control") over a 72 minute interval over 8 weeks. (Since it took twice as much time to test the toggle-controlled device, the value of the “day” axis was divided by 2 to achieve a comparable curve.)
As can be seen from FIG. 18, the on / off circulation of the core device causes a significant increase in the evaporation rate from the device. The photograph in FIG. 15 provides evidence that on / off cycling significantly reduces wick clogging.

Example 4: Larger pore size improves evaporation characteristics When it was discovered that clogging of the core was responsible for reducing evaporation and that evaporation could be increased by reducing clogging A further step was taken to identify a method for improving evaporation. This example shows that evaporation is increased by increasing the pore size.

  Briefly, an AIR WICK® Country Belize® fragrance device is used with two cores: a) an average pore size of 36 microns and b) an average pore size of 73 microns. And tested. The two wicks were tested by operating them sequentially by turning the device on and off with a toggle switch for longer than a month. FIG. 19 shows the result.

  As can be seen, within the first week, the large pore size core performed significantly better than the small pore size core. This difference decreased in the second week and disappeared by the third week. This convergence at low performance is believed to be due to clogging of the core. Clogging of the wick occurs much earlier with small pore size wicks than with large pore size wicks. From these experiments, it can be concluded that the large pore size core produces better evaporation than the small pore size core.

Example 5: Shorter cores work better Additional studies were conducted to determine if other characteristics of the core could improve evaporation properties. This example shows how evaporation can be improved by reducing the length of the wick.

  Briefly, using AIR WICK® Country Berries® fragrance device, two 73 micron wicks, a) 75 mm long and b) 85 mm long And tested. The two wicks were tested by operating the device continuously for more than one month. The apparatus was turned on and off alternately every 72 minutes. During the “on” portion of each cycle, the heater temperature was 70 ° C. FIG. 20 shows the result.

  As can be seen, the shorter core produced a more stable evaporation characteristic. After more than 3 weeks of use, evaporation was only reduced by about 25%, while evaporation from the long core was reduced by more than 50%.

Example 6: Determination of circulation time An additional study was conducted to determine the cycle time to achieve the most desirable fragrance release for a twin-core system.

  Briefly, two AIR WICK® Country Berries® fragrance devices were tested. The first time was alternately turned on and off every 30 minutes. The second time was turned on and off alternately every 72 minutes. Release was measured using a photoionization detector (PID), Photovac 2020 model. The results were plotted against time. In each case, the recorded results were additionally shifted by 30 and 72 minutes, respectively, in order to simulate a second identical scented substance release core. The plots are shown in FIGS. 21 (a) and (b).

  As can be seen, the 30 minute cycle time for the twin-core system achieved the most desirable level, ie, the lowest peak: valley ratio for the simulated combination curve. However, it should be noted that longer cycle times can be effective for three-core systems. The theoretical ideal is the core of an infinite number. Obviously, fewer cores are required from a practical point of view, and 2, 3, 4, or 5 cores may be more practical.

Example 7: Determining the effect of cycle time on volatilization An additional study was conducted to determine the effect of cycle time on the volatilization of a perfume composition from a single core system.

  Briefly, four AIR WICK® Country Berries® fragrances were used in this study. The core was made of porous polyethylene having an average pore size of 73 microns, an average pore volume of 38%, a length of 85 mm and a diameter of 6.8 mm. During the “on” part of each cycle, the temperature of the heater was 70 ° C., and an average core temperature of 60 ° C. was obtained based on temperature measurements at the top of the core (hot part) (with the temperature probe at the top of the core) Arranged). The first device was turned on and off alternately every 15 minutes. The second device was turned on and off alternately every 30 minutes. The third device was turned on and off alternately every 45 minutes. The fourth device was turned on and off alternately every 72 minutes. Emission was measured using a photoionization detector (PID), Photovac 2020 model. The test site was a 10 × 10 foot (3 × 3 m) room with ambient temperature and airflow.

  After using the device for 2 weeks and then for 4 weeks, the release was tested for each core. The PID sensor was positioned approximately 5 mm above the top center portion of each core. Release was sampled once per minute at peak release (first release after heat was applied to the core) and through three complete on / off cycles. For example, at 2 weeks for the third device, the release is sampled once per minute for a total sample time of 270 minutes; again for the first device, at the 4 week time point, for a total sample time of 270 minutes. The release was sampled once every minute. An electrical reading from the PID was captured and the average concentration of perfume at the top of the wick during the measurement period was quantified in parts per million. One result of such a study is shown in Table 11.
